The SambaRack SN40L-16 rack networking devices are preconfigured during installation. In some cases, administrators may need to perform limited post-installation administrative tasks, as described in this document. For additional details, refer to the Third-party component documentation.
The Juniper QFX5130 port 16 will show an amber light. This is expected behavior and not a warning condition.
Password administration
SambaRack and Core Services Racks ship with default usernames and passwords for all devices. Please see SambaNova support KB article #1411 for the default credentials. Administrators are strongly advised to change these at the first opportunity.
SambaRack Manager must always be updated with the latest device credentials.

Run the following commands:
ssh root@<Juniper_switch_IP_address>

Step 2: Log out
Log out of the switch by using the exit command three times:
- To exit config mode
- To exit operational mode
- To exit the Linux CLI
Step 3: Verify the new password
Log back into the switch with the new password to confirm the change was successful.
Step 4: Update SambaRack Manager password vault
If SambaRack Manager is installed and set up, it must be updated with the latest credentials to ensure proper operations. See the Set Secret section for more details.
